[PATCH] Create.c: close mdfd and generate uevent

[Mariusz Tkaczyk <mariusz.tkaczyk@linux.intel.com>]

During mdfd closing change event is not generated because open() is
called before start watching mddevice by udev.
Device is ready at this stage. Unblock device, close fd and
generate event to give a chance next layers to work.
